The 2007 Stromboli eruption: Event chronology and effusion rates using thermal infrared data

Abstract

[1] Using thermal infrared images recorded by a permanent thermal camera network maintained on Stromboli volcano (Italy), together with satellite and helicopter-based thermal image surveys, we have compiled a chronology of the events and processes occurring before and during Stromboli's 2007 effusive eruption. These digital data also allow us to calculate the effusion rates and lava volumes erupted during the effusive episode. At the onset of the 2007 eruption, two parallel eruptive fissures developed within the northeast crater, eventually breaching the NE flank of the summit cone and extending along the eastern margin of the Sciara del Fuoco. These fed a main effusive vent at 400 m above sea level to feed lava flows that extended to the sea. The effusive eruption was punctuated, . In this paper, we discuss similarities and differences between these two effusive events and interpret the processes occurring in 2007 in terms of the recent dynamics witnessed at Stromboli.Citation: Calvari, S

Satellite and Ground Based Thermal Observation of the 2014 Effusive Eruption at Stromboli Volcano

“…The reason behind this lies in the poor knowledge of precise values for some parameters in Equation (7). As previously proposed [5,6,23,55], we thus provide two datasets ranging from the lowest (min TADR) to the highest possible estimate (max TADR). The used parameters are listed in Table 6.…”

“…Continuous effusive activity is uncommon for Stromboli. During the last decades, only three major effusive episodes were recorded: 1985/86 [3], 2002/03 [4,5] and 2007 [6][7][8]. The effusive activity presents no direct hazard to the island's inhabitants.…”

Susceptibility of intrusion-related landslides at volcanic islands: the Stromboli case study

“…5c). The areas with higher probability of intrusion-related landslides are located in the upper part of the SdF, the same area characterized by the occurrence of mass-wasting during the 1985flank eruptions (De Fino et al 1988Calvari et al 2005Calvari et al , 2010Carlà et al 2016). The other area showing moderate susceptibility to intrusion-related landslides is the Rina Grande-Le Schicciole depression.…”

“…2) are common and frequently associated with the effusive phases. At the onset of the 1985, 2002-2003, 2007 and 2014 flank eruptions, gravel/debris slides evolved in dry gravel/debris flows along the SdF following the opening of eruptive fissures on the NE flank of the summit cone (De Fino et al 1988;Calvari et al 2005Calvari et al , 2010Carlà et al 2016). During the 2012-2013 high-intensity strombolian activity, overflows occurred and were often associated with the sliding of the NEC craterrim (Di Traglia et al 2014b;Calvari et al 2016).…”

“…Andronico et al, 2005;Dean et al, 2004;Dehn et al, 2002), and once an eruption begins, temperature plays a major role in lava flow emplacement and lava field development (e.g. Ball et al, 2008;Calvari et al, 2010;Lodato et al, 2007). At active volcanoes, temperature has been measured by direct and indirect methodologies (Fig.…”
